Setup
Connecting the Headphones
The MH100 headphones utilize a standard 3.5mm audio jack for connectivity.
- Locate the audio output port on your device (e.g., audio interface, mixer, computer, or portable player).
- Insert the 3.5mm jack of the MH100 headphones firmly into the device's audio output port.
- Ensure the connection is secure to prevent audio interruptions.
Adjusting for Comfort
The headband is adjustable to fit various head sizes. Gently slide the earcups up or down along the headband until they rest comfortably over your ears.
The earcups are designed to provide sound isolation. Ensure they form a seal around your ears for optimal audio performance and comfort.
Operating Instructions
Audio Playback
Once connected, play audio from your source device. Adjust the volume level on your device to a comfortable listening level. Avoid excessively high volumes to protect your hearing.
Sound Isolation
The closed-back design of the MH100 headphones provides passive noise isolation, reducing external distractions and preventing sound leakage. This feature is beneficial for studio monitoring and critical listening environments.

Maintenance and Care
Cleaning
To clean the headphones, use a soft, dry cloth. For ear cushions, a slightly damp cloth with mild soap can be used, but ensure they are completely dry before use. Do not use harsh chemicals or abrasive cleaners.
Storage
When not in use, store the headphones in a clean, dry place away from extreme temperatures and direct sunlight. Avoid placing heavy objects on them. The MH100 headphones can be folded for compact storage.
Cable Care
Avoid sharply bending or twisting the audio cable. Always grasp the plug, not the cable, when disconnecting from a device.
Troubleshooting
No Sound
- Ensure the 3.5mm audio jack is fully inserted into both the headphones and the audio source device.

- Test the headphones with a different audio source or device to rule out a device-specific issue.
- Inspect the cable for any visible damage.
Distorted Sound
- Reduce the volume level on your audio source.
- Ensure the audio source is playing a high-quality audio file.
- Check for loose connections.
Poor Sound Isolation
